Abstract

Based on published data and material from several Ordovician sections of the Siberian Platform and northeastern Russia housed in the Paleontological Institute of the Russian Academy of Sciences, the ostracode family Egorovellidae Schallreuter, 1966 is revised. The family is of great importance for biostratigraphic correlation. The diagnosis of the genus Bodenia V. Ivanova, 1959 is clarified and two new species, B. signata sp. nov. and B. densistriata sp. nov. are described. Two species previously included in Bodenia are removed from the genus and assigned to the family Richinidae: B. aechminiformis is designated as the type species of the new genus Bodeniella gen. nov. and B. anonyma is assigned to the Siberian genus Angarallina Melnikova, 2020. Two new species of the genus Egorovella, E. porilamellata sp. nov., and E. insperata sp. nov., are also described.
